10 Kirkland Items You Should Always Buy at Costco

Liquor

Across the board, Costco’s value-sized bottles of booze get rave reviews. Its vodka in particular has garnered a cult following, with rumors swirling that it shares the same water source as Grey Goose. The luxury vodka brand denies those claims, but that’s not necessarily a bad thing—the cheap Kirkland version actually outshines Grey Goose in taste tests. Just $25 for 1.75 liters of high-quality liquor? Can’t beat that.
